Issue/Introduction

Activemq will not start.

Activemq fails with error - Could not load xbean factory:java.lang.NoClassDefFoundError:

 

 

We are running fault tolerant DA’s and when we put the DA in activate it starts but activemq fails.

/opt/IMDataAggregator/broker/apache-activemq-5.16.4/data/activemq.log

In activemq.log we see:

Loading message broker from: xbean:activemq.xml
ERROR: java.lang.RuntimeException: Failed to execute start task.

Reason: java.io.IOException: Could not load xbean factory:java.lang.NoClassDefFoundError: org/springframework/core/NestedRuntimeException
java.lang.RuntimeException: Failed to execute start task. Reason: java.io.IOException: Could not load xbean factory:java.lang.NoClassDefFoundError: org/springframework/core/NestedRuntimeException

 

Journalctl -xe adds no insight.

All permissions seem right.

Environment

Release : 21.2.10

Cause

Anti-virus scans had removed a needed jar file from the PM-Install path

/opt/IMDataAggregator/broker/apache-activemq-5.16.4/lib/optional/spring-core-4.3.30.RELEASE.jar

Resolution

Copied the missing file from a 21.2.10 lab
